The Name of Prophet Nuh نوح alayhis-salaam.
His real name was عبد الغفار Abdul-Ghaffaar.
Nuh is a non-Arabic name but is mu’arrab (the last letter can accept kasra and tanween).
The origin of the name is Syriac and it means الشاكر “The Thankful”.
In Arabic نوح means to cry or weep.
He was given the name Nuh because of the abundant amount of times he cried over himself.
